Which among the following is not true regarding diphtheria carriers?
Correct Answer: Immunization prevents carrier state
Description: Immunization doesn't prevent carrier state. It only prevents infection. Human carriers are the main reservoir of infection. Infected patients and asymptomatic carriers can transmit C diphtheria respiratory droplets, nasopharyngeal secretions, and rarely fomites. The greatest propoion of carriers is in the age group 1 to 5 years, and owing to the small size and anatomical complexities of the nasal passages, the pathological conditions tend to persist and make examination and treatment difficult. Treatment of contacts is necessary.
